ABSTRACT:
An inspection device for inspecting projections of a part which can be applied to a variety of parts having projections on the surface thereof such as leads of electronic parts having varying shapes. The inspection device includes a member having a two-dimensional surface to which projections of the part are two-dimensionally pressed at a predetermined pressure, and an arrangement for detecting a pressure distribution pattern on the surface of the member as well as a converter for converting the detected pattern to two-dimensional pattern information. Further, a memory is provided for storing a reference pattern of the projections of the part so that inspection may be effected by comparing the reference pattern with the converted two-dimensional pattern information.
